Protect concrete with Opti-Seal

Opti-Seal Penetrating Concrete Seal

Biobased technology that doesn’t harm the environment

Opti-Seal Penetrating Concrete Seal is the best choice for preserving any concrete surface. The deep-penetrating solution stops Alkali Silica Reaction (ASR) and seals out moisture. Concrete preserved with Opti-Seal is stronger and lasts longer in all climactic conditions.

Once Opti-Seal is sprayed onto the concrete surface, it can penetrate up to 4 inches and seals out moisture from the surface down. Green nanopolymers stop ASR and work as a deterrent of rust on embedded rebar.

Moisture soaks in versus wicks on top

Opti-Seal prevents ASR and reinforcement deterioration

ASR breaks down concrete strength, leading to structural issues if not addressed properly. While conventional sealants sit on top of the surface, a single application of Opti-Seal penetrates deep into the concrete and creates a protective barrier against moisture and penetrates to stop ASR from further damage.

The unique chemistry also adds a protective coating around the reinforcement within the concrete that prevents rusting.

Applied with precision

With our customized spray system that controls the application rate, Opti-Seal goes on with precision and accuracy, ensuring the solution only goes where it should.

Opti-Seal can also be applied with standard spraying equipment to vertical concrete surfaces like bridges, road barriers and tiles.
